By this is understood that on cleaning a field of cane which has beenrecently planted, the tractor can circulate, resting its wheels on theridges turned up by the plough on e ch side of the furrow 8 where thecane is planted and the plough shares of the cultivators 5 willperfectly-clean the ridges in all their width of grass, parasites, etc.

lllhen the growth of the cane reacl es a height where it preventsprogress of the tractor above the furrows l provide auxiliary means oraccessories as represented in Figures 6, 7 and 8 of the drawings whichpermit circulation of the tractor over the plants.

In Figure 6 is represented a narrow rectangular plate 9 of the samelength as plate 2 and doubled downwards at its sides to form horizontalflanges 9 provided with bores 9 correspond as seen with the bores 2 ofthe plate 2 and having in the center of said plate 9 three bores 9corresponding with the bores 2 of the plate 2.

ln Figures 7 and 8 is shown a demountable wheel-tire of greater diameterthan the rear wheels 6 of the tractor, provided radially with spacedbolts 11 fixed therein which have nuts and counter nuts 12 and 13.

The plate 9 as shown in Figures 3 and 4t is placed below the plate 2 sothat the holes 9 coincide with the bores 2 of plate 2 fixing both platestogether with bolts 14 and being able to fn; in the eXtreme bores 9 theengagements 5 of the cultivators 5.

The wheel-tires 10 are installed by arranging them in concentricalrelation with the back wheels G of the tractor passing' the bolts 11through the bores provided previously in the wheels 6 coinciding withsaid bolts, these wheels remaining between the nuts and counter nuts 12and 13 of the bolts 11 and these acting as illustrated in Figures 3 andt as spacingmembers of the demountable wheel-tire 10 with regard to thewheel 6 it being evident that the separation between both wheels 6 and10 will be equivalent to the vertical separation between the ends of theplates or engagement members 9 and 2 with the object of always maintain'ing the engagement member at a horizontal plane su'liicient toadequately connect the cultivators 5.

At the same time the wheel-tires 10 are provided with usual spikes 14 orthey can be taken from the interior wheels 6 of the tractor 4 to applythem to the periphery of the demountable wheel-tire 10.

r'he tractors 4 thus equipped can circulate over the fields even whenthe plants or shoots 15 have reached certain growth esteeming' thisgrowth to be sufficient for the plants not to need any further cleaningor cultivation.

As may be easily understood, especially by those e311 ert in the art towhich this invention pertains, the advantages of time and economy gainedby being able to apply a tractor to these labors are enormous, it beingsufficient to-day that the help plants or cleaning of six hundredfurrows in a plant ed field needs the work of a pair of oxen and a manduring twenty days, and this operation can be performed with the use ofthe tractor in one day only.

Although i have referred to a tractor in this descriptive memorandum, Iwish to state that by this word I mean any kind of motor vehicle whichmay be considered adequate for agricultural labor use.

llt should also be noted that it is possible to engage more than twocultivators to the tractor simply by increasing the length of the platesor engagement members 2 and 9 arranging the bores of the engagement 2and 2 in separations equivalent to the width of a furrow and in the samemanner introduce any modification in the re-inforcement or form of theframe.

rllherefore it should be understood that I d o not limitmy riOht ofLetters Patent to what has been previously mentioned, but I wish toreserve the rightl to make all variations that would be compatible withthe substantial idea of the invention which is as claimed in thefollowing.

Claims:

1. A draft attachment, comprising, a connecting head, a draft bar firedto the head and a plurality of series of apertures in the bar, theseries being spaced a distance equal to the width of afurrow, incombination with an adjusting bar, a central offset portion on theadjusting bar, centrally positioned matching apertures in the draft andadjusting' bars, and a plurality of series of apertures in the adjustingbar corresponding with said series of apertures in the draft bar.

2. A draft attachment, comprising, a connecting head, a draft bar fixedto the head and a plurality of series of apertures in the bar, theseries being spaced a distance equal to the width of a furrow, centrallypositioned apertures in said bar, in combination with an adjusting barconnectible to the draft bar, demountable rims for the wheels of atractor with which the detachment is used, the rims increasing theeffective diameters of the wheels, and the adjusting bar maintainingconstant the height of the attachment above the ground.

3. i draft attachment, comprising, a connecting head, a draft bar fixedto the head to the Width 0'1": a furrow, in combination with anadpistlng bar, a central offset portion on th-e adjusting bar, centrallypositioned matching apertures in thev draft and adjusting bars, andaplurality of series of apertures in the adjusting bar correspond-` ingwith said series of apertures in the draft bar, deinountabie rinis forthe Wheels of a 19 traetorwith which the detachment is used, the rimsincreasing the effective diameters of the Wheels, and the adjusting barmaintaining constant the height of the detachnient above the ground.

In testimony whereof I have signed my naine to this specification.
